ROBERT A. GAIaLY, OF CINCINNATI, OHIO, ASSIGNOR TO THE BALDWIN COMPANY, OF

- CINCINNATI, OHIO. I

music-PLAYER VALVE.

To all whom it may concern Be it known that-I, ROBERT A. GALLY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Music-Player Valves, of which the following is a specification.

This invention provides a more accessible and easily cleaned valve and return vent than previous devices, and more ready ad- .justment of the valves to their seats and throw and to the pouch.

In my previous applications #7 30,635 and #749,812, are shown a valve rod loosely guided in a hole in the pneumatic follower and removable with its valves carried thereon, but in this present application improvements are made for easy access and regulation, and a speclal arrangement of return vent is included. Clalms are appropriately distributed in the three applications, no

. waiver of any rights being intended.

In the drawings Figure 1 is a View of a valve chest from its top, the rails of the chest partly cut away to show the valves, chambers and pneumatics; Fig. 2 a rear view of a pneumatic follower or button Fig. 3

- -a view of a rod and valves as removed from the chest; Fig. 4 a front view of the same chest with portions removed to show interior parts; and Fig. 5 is a modified view of the removable valve rod with screw adjusters "to regulate it to the extension of the pneu- ,matic.

or caps 4, "such caps being removably attached to the front face of the valve rail 3 by. screws 5 or the like to allow removal -when access is desired to the valves or vents .now to be .described. A valve-rod 6 carries suitable valves 7 and 8 mounted thereon, a collar 9 on said rod serving to hold the valves 7 and 8 in their position lengthwise of said rod 6, while a separator10 or other suitable means holds the two valves at a proper spread to give the correctplay between their seats 11 and 12. Such play may ward of its collar 9' and is loosely guided in a hole 14 in the extension body or stem 15 of the button or follower 16. The collar 9 of rod 6 takes the thrust from stem15 of.

follower 16 when actuated by the pneumatic Specification of Letters Patent.

17, the latter being preferably of pouch form.

The stem 15 is preferably made long I enough to extend forward into the port of the inner valve 7, allowing a long guidance for the rear part of rod 6 in the hole 14 of stem 15, thus insuring against accidental displacement of the rod from the hole, and

making easy the inserting of the rod in the hole when the rod and its valves are replaced in the hole after removal for any purpose.

The removal of the rod 6 with the valves 7 and 8 complete thereon, is much easier than picking off the valves from such a rod that is attached to its pneumatic.

The exact freedom or excess safety motion of pneumatic 17 to allow the seating of valve 7 on inner seat 11, may be nicely adjusted by washers or chips 18 placed between the collar-9 and the stem 15, against which said collar 9 bears.

When the cap 4 is removed, the rod 6 and its valves 7 and 8, etc., may be readily removed at a unit, without separating the valves, etc., from the rod. Any dirt may thenbe cleared from the valves, the valves regulated on the rod, the regulation of collar 9 to the stem 15 changed, or view and access 'had to pouch 17, follower 16 and its stem 15,

as also to the bleed or return-vent 19 in the disk 20'set on the rear of follower 16. This vent 19 is preferably in axial alinement with the hole 14 of stem 15, thus allowing sight and access to the vent through said hole 14 from the front of the action when valves are removed. An air hole 21 connects the air of the chest 1. to the vent 19, preferably on a straight line to the vent. This position of the vent 19 being opposite the centrally positioned duct 22 entering the rear of the pouch 17 also allows access to the vent through said duct 22 from the rear, .and a clear sight throughvent 19 and duct 22 and hole 14 of stem 15, either from the frontof stem and action, or from the rear 'of the action and the duct.

While the vent 19 may be formed in the material of the follower itself, if such material is suitable, any substance, as wood, may be used for the follower and the vent 19 made in a thin plate or disk 203s of celluloid and set into a socket 23 in the rear of follower 16, and the leather of pouch 17 "sealed over it. The central position'of the vent in the follower permits a small central g'umming of the leather of the pouch 17 to the follower 16, thus having a free pouch.

Suitable modifications and adaptations of this invention may be made and still besubject to what I claim as my invention.
